A Week Focused on Color

Color Science and Engineering Systems, Technologies, and Applications

Join us for a week of color-related courses, workshops, paper presentations, exhibits, andinteresting conversations around technical topics and application areas related to color!

Please note, change in program schedule: We’ve made some changes to the weeklylayout. This year CIC has two tracks of short courses on Monday—our one-day Colorand Imaging course plus a track of Advanced Topics—and four tracks on Tuesday untilmid-afternoon. Workshops, which have traditionally been held on Friday, have beenmoved to mid-afternoon on Tuesday, followed by the welcome reception, then three fulldays of keynote talks and technical papers. We are also introducing Colleague Connection gatherings during coffee breaks where those interested in discussing a topiccan get together informally. See page 5 for details on one Connection; if you’re inter-ested in hosting a topic, contact [email protected].

We hope you like these changes and wel-come your feedback. Please help us get theword out about this amazing annual event andprepare yourself for a great week in Canada.We're looking forward to seeing you and enjoying an excellent conference together!

OPENING KEYNOTEA Brief Story of SuperpixelsRadhakrishna Achanta, Swiss Data Science Center (Switzerland)

The number of pixels in images is steadi-ly rising. While computing power andmemory are getting cheaper, it is never-theless difficult for algorithms to dealwith memory and computational burdensposed by large images, image-stacks,and videos. To address the need to re-duce the processing burden, superpixelswere introduced and have since foundtheir way into a large number of applications.

Superpixel segmetation algorithmsneed to be efficient in computation andmemory consumption to be useful. In ad-dition to touching upon the state-of-the-art, general approaches, and applica-tions of superpixels, this talk presentsthree efficient superpixel segmentationalgorithms. The first one is Simple LinearIterative Clustering (SLIC), the second isa variant of this called Simple Non-itera-tive Clustering (SNIC), and the third is analgorithm that relaxes the requirement ofhaving roughly equal size.

COLLEAGUE CONNECTIONExpanded Gamut Printingduring the Wed. morning coffee breakConvened by Abhay Sharma, RyersonUniversity (Canada)

A new topic in traditional printing is toexpand the color gamut using colorantssuch as orange, green, and violet, givinga CMYK + OGV process. This emergingtechnology is applicable to all printingprocesses—inkjet, digital, offset, flexog-raphy. Most inkjet proofers already usean expanded gamut ink set and thereare many new digital presses withCMYK+ color capabilities. Pantone hasa new swatch book, the EXTENDEDGAMUT Guide - printed with 7 colors.Join this informal meeting to understandthe challenges and opportunities of expanded gamut color printing.

WEDNESDAY EVENING TALKColor in Narrative, Andrea Chlebak,feature film colorist (Canada)

Color is an often subtle layer in theprocess of filmmaking. It adds dimensionby enhancing or creating atmosphere,calling attention to certain details, oradding meaning by establishing apalette to a certain character. As a supervising colorist for feature, documen-tary, and commercial films, the speakersheds light on the process of coming to afinal look for a film; she’ll discuss her useof experimentation, intuition, and percep-tion as a toolset to determine how blue,dark, or saturated to make an image,and how she collaborates with directorsand cinematographers to enhance thenarrative through color.

THURSDAY KEYNOTEColour and Consumer Cameras:The Good, the Bad, the UglyMichael Brown, York University (Canada)Sponsored by HP Inc.

Cameras are now used for many pur-poses beyond taking photographs. Ex-ample applications include remote med-ical diagnosis, crop monitoring, 3dreconstruction, document recognition,and many more. For such applications,it is desirable to have a camera act as asensor that directly measures scene light.The problem, however, is that most com-modity cameras apply a number of cam-era-specific processing steps to the cap-tured image in order to produce visuallypleasing photos. As a result, differentcameras produce noticeably differentcolors when imaging the exact samescene. This is problematic for applica-tions relying on color because algo-rithms developed using images from onecamera often will not work with imagescaptured on another camera due to col-or differences. In this talk, I’ll discuss thecurrent state of affairs for color on com-modity cameras, common incorrect as-sumptions made in the scientific litera-ture regarding image color, and recentdevelopments that are helping to im-prove the situation

CLOSING KEYNOTEHigh Dynamic Range on the Big ScreenAnders Ballestad, CEO and co-founder,MTT Innovation Inc., a Barco Company(Canada)

High dynamic range (HDR) is slowlymaking its way to the big screen afterfirmly being established in the livingroom. For the cinema, there is consider-able excitement around high-contrastprojectors as well as LED walls. MTT hasdeveloped an HDR projector based on anew image formation technique wename dynamic lensing. Source light issteered from dark regions to bright im-age areas, with dramatic results: deepblack levels and a peak luminance ex-ceeding TVs and LED-walls using similarstrength light sources as conventionalprojectors. The perceptual impact ofdrastically enhanced colour volume tech-nologies will be discussed, as well as anumber of open questions around thecreative workflow and the potential fornew experiments in color science.

W1: Virtual and Augmented Reality: Challengesand Perspectives15:45 – 18:15Chair/Convener: Giuseppe Claudio Guarnera,NTNU (Norway)

Over the past few years Virtual Reality andAugmented Reality have become widelyavailable in consumer devices, promising totransform the way we think, learn, and com-municate. The capability of creating photo-re-alistic, rendered objects within a real-worldsetting will support sale, promotion, accuratevisualization, planning, and marketing pur-poses more and more in the coming years. Akey factor common among all the countlesspossibilities offered by AR and VR is that allthe depicted materials, their reflectance prop-erties, the lighting, etc. must be consistentwith human perception and across differentplatforms.However, photo-realism is still a challenge

even on desktop environments, and AR/VR israising the bar for efficient, realistic, andcost-effective material modelling, given thelow power and thermal budget of wearableAR/VR headsets and the increased computa-tional demand (visual artifacts are distractingand look worse in immersive 3D environ-ments). Therefore, most VR experiences arecurrently limited to omnidirectional stereo ren-

dering, with no freedom to move around thescene; only in the last few months has the po-tential of light fields begun to be explored.This workshop discusses the current chal-

lenges (such as limitations in both hardwareand software) and attempts to exploit humanperception of color, materials, and lighting toovercome them. Overall, the workshop willhelp academic and industry researchers toaddress the societal needs created by thesenew tools (sense of immersion, social pres-ence, etc.), in order to unleash their potentialfor new applications.

Call for Speakers: Researchers who want toparticipate in the discussion or to give a pres-entation are welcome to submit their propos-al for review via [email protected] (subjectline: AR-VR Workshop Proposal). The goal isto encourage discussion and exchange ofideas.

Each part of this process has seen a tran-sition, from film scanning to digital editing,digital camera, digital workflow, vfx, in-crease of resolution, wider color gamut,wider dynamic to faster fps, etc. Slowly, butsurely, the digital workflow is approaching alevel of quality and usability which seemedimpossible a few years ago.Often, the words used to describe new fea-

tures can be misleading, especially when itcomes to HDR, which is more than wider dy-namic and or wider gamut available to thecreators. In the end, the spectator is experi-encing the movie on a display that may ormay have HDR capabilities.What are the implications for a movie’s

production when it has been decided that itwill be an HDR movie? In this workshop,speakers representing key positions and/orprofessions from the movie production work-flow, introduce their activities, from colorist,VFX supervisor, color pipeline, cinematogra-pher, display engineer, etc. in relation toHDR to help us understand how their practiceis evolving with this technology.Each speaker will give a 15 min presenta-

tion; after the presentations, there will be agroup discussion with Q&A.

Confirmed speakers as of July:● Sean Copper (DoubleNegative) VFX/Fea-ture animation: HDR—What has and hasn't changed including OpenEXR,

OpenColorIO, review of material, rangeof “safety” checks, on-set grades, qualityof review displays, HUNDREDS of peoplecreating, manipulating, and defining the final image

● Chris Davies, HDR Post-production:Impacts on production, workflow, and infrastructure from onset equipment, cam-eras, monitoring, exposing, metering todailies, lighting, displays, lessons learned,and solutions needed.

● Timo Kunkel (DOLBY) Image Display:Reproducing the appearance of real worldluminance levels in a plausible way, in-cluding feeling or mood, scene vs displayreferred, higher max luminance levels,deep black levels, and an overview of fun-damental technical concepts of HDR dis-plays such as dual modulation (LED-LCD,LCD-LCD), direct emissive display (OLED),Micro LED, HDR projection
